Comparison of alphanumeric notation, Palmer notation, ISO 3950 (FDI) notation, Universal Numbering System, and paleoanthropology notation. Dental professionals, in writing or speech, use several different dental notation systems for associating information with a specific tooth.
[1] [2] It is designated by the International Organization for Standardization as standard ISO 3950 "Dentistry — Designation system for teeth and areas of the oral cavity". [ 3 ] The system is developed by the FDI World Dental Federation .
It is possible for the soft palate to retract and elevate during speech to separate the oral cavity (mouth) from the nasal cavity in order to produce the oral speech sounds. If this separation is incomplete, air escapes through the nose, causing speech to be perceived as nasal .
The shape and position of the tongue (the place of articulation) determine the resonant cavity that gives different stops their characteristic sounds. All languages have stops. Nasal, a nasal occlusive, where there is occlusion of the oral tract, but air passes through the nose. The shape and position of the tongue determine the resonant cavity ...

The mouth consists of two regions: the vestibule and the oral cavity proper. The vestibule is the area between the teeth, lips and cheeks. [3] The oral cavity is bounded at the sides and in front by the alveolar process (containing the teeth) and at the back by the isthmus of the fauces. Its roof is formed by the hard palate.
The hard palate is formed by the palatine process of the maxilla and horizontal plate of palatine bone.It forms a partition between the nasal passages and the mouth.On the anterior portion of the hard palate are the plicae, irregular ridges in the mucous membrane that help hold food while the teeth are biting into it while also facilitating the movement of food backward towards the larynx once ...
The incisive foramen is a funnel-shaped opening in the bone of the oral hard palate representing the inferior termination of the incisive canal. [citation needed] An oral prominence - the incisive papilla - overlies the incisive fossa. [1] The incisive foramen is situated immediately behind the incisor teeth, and in between the two premaxillae.
